Palpada is a genus of 85 neotropical and nearctic flower flies or hoverflies[1][2][3][4] This genus is often colorful and bee-like. It is in the tribe Eristaliini containing dozens of genera [1] Common sister genera include Eristalis (99 species), Meromacrus (43 sp.), Eristalinus (100 sp.) and Helophilus (50 sp.). The genus palpada is distinguished by:

  • Eyes with uniform pile.
  • Meron with fine pale hairs in front of or below spiracle.
  • Hind femur with basal patch of dense black setulae.
  • Cell r2+3 closed before wing margin.
  • R4+5 moderately to strongly dipped into cell r4+5.[1]

The larvae are aquatic and have a distinctive shape, usually being referred to as rat-tailed. The rat-tail is a breathng tube that allows the larvae to live in low oxygen water.
